Hello John,
oh yes, you are right. I hope this explains it more precicely:
I have 3 servers in total,
server A and server B have a filedaemon and a storage daemon each, and server
C has a director that controls both server A and B.
Here is a little ascii-art picture ;-)
Server A Server B
LTO3 Drive LTO3 Drive
Filedaemon Filedaemon
| |
--------------
|
ServerC
Director
Catalog DB
Usually, every server makes backups on its own drive and restores from its own
drive, which works without problems.
But when I try to make a restore on the other server, I have to make a little
backup first on the other storage/drive to be able to do a restore.
It seems that somehow the director does not really understand that the correct
tape is already mounted, but it IS mounted.
After doing a little backup on this tape, the director understands that the
tape is mounted there an then the restore just works like expected.
As this works, I can tell that I have no problems with wrong media type etc.
thank you for asking for more info, I hope this makes it clearer.
best regards,
Philipp
